Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145966, here are decompositions:
- 3 + 145963 = 145966
- 17 + 145949 = 145966
- 137 + 145829 = 145966
- 167 + 145799 = 145966
- 257 + 145709 = 145966
- 263 + 145703 = 145966
- 389 + 145577 = 145966
- 419 + 145547 = 145966
Showing the first eight; more decompositions exist.
